I'm curious about pfsense users' experience of using the platform instead of, for example, Watchguard. We have two sites with dual XTM 5xx series units in fail-over and they work fine, but we don't use any of the extra licensed features so they are just firewalls (we do use the SIP app gateway but I don't know whether we benefit from it over a standard firewall rule).
The cost per annum is pretty high so I'm considering alternatives for when it comes up for renewal. Any experiences from people who have made this specific move ?
